three weeks ago, I had a filling done on one of my back molars. After the filling was done, she corrected my bite some by drilling it back down, but she also drilled on the top tooth that was going to come in contact with it when I bite down. That top tooth has a crown. Now I have pain and sensitivity in that tooth. Is it normal to drill on the top tooth to fix a filling on the bottom? And is there anyway to calm the nerves down in the top tooth? Do I need to get my bite adjusted?
